In this paper, advanced economies are aggregated into ‘North’ whereas ‘South’ comprises the less advanced ones. Trade induced technology diffusion is source of enriched technological contents. We also consider two scenarios: (i—"hub and spokes [HAS]") the North establishes separate bilateral FTAs with each South; and (ii—"FTASS") Southern economies jointly establish a full-fledged FTA with North. Simulations confirm that: (i) North- South and South-South trade-led technology diffusion induces TFP-growth; (ii) relatively less developed South catches up; (iii) three regions experience welfare improvement; and (iv) IT-enabled E-commerce facilitate trade. Public policies play role in catalyzing international competitiveness, innovativeness and absorption.
